AXLE-BOX FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 400,545, dated April 2, 1889. Application filed July 7, 1888. Serial Ho. 279,270. (No model.)

To all whom it may concern:

Be it known that I, RANSFORD T. CHASE, of Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Axle-Boxes for Locomotives, of which the following is a full, clear, and exact description. 1 I

The object of the invention. is to provide certain'new and useful improvements in axleboxes for locomotives, by which the centers of the axles always remain the same distance apart.

The invention consists of certain parts and details and combinations of the same, as will line so x-of Fig. 1.

The pedestals A of the locomotive are each provided with guideways B B, in which is mounted to slide vertically the axle-box O, of any approved construction and mounted at the respective end of the axle D. On the pedestal A is also formed a vertical guideway, E, in which is mounted to slide up and down at one side the axle-box F, of any approved construction, and mounted on the axle Gin the usual manner.

On the inner end of the axle-box F is secured a rod, H, pivotally connected at its other end by a bolt, I, to a lug, C, on the axle-box O. The rod H thus connects the axle-box O with the axle-box F in such a manner that the centers of the axles D and G must always remain the same distance apart, and consequently when the axle-box 0 slides vertically in its guideways B the rod H causes the axle-box F to travel with its center in the line of an arc of which the center of the axle D is the center. As the axle-box F is guided only at one end, it permits the arc movement above described.

Three axle-boxes on one side of the locomotive may be connected with each other by connecting the left end of the axle-box O with the third axle-box by a rod, H, in the same manner as shown in Fig. 1 for connecting the axle-box C with the axle-box F. Any number of axle boxes may thus be connected with each other, so that the centers of the axles always remain the same distance apart. Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a truck having vertically-sliding axle-boxes and ways therefor, of avertically-swinging rod rigidly secured at one end to one box and hinged at its oppo- RANSFORD T. CHASE.
